Answer

Answer:

a. A dissolves faster.

Explanation:

Step1: Consider surface - area factor

Powdered sugar has larger surface area, but...

Step2: Consider temperature factor

Higher temperature (25°C in A vs 10°C in B) increases dissolution rate. The temperature effect dominates here as the increase in temperature has a significant positive impact on the dissolution rate of sugar in water, outweighing the surface - area advantage of powdered sugar in sample B. So, cubed sugar in 25°C water (sample A) dissolves faster.
